The pump outlet fitting on the high-pressure hose uses a ferrule and compression fitting. The wedge-shaped ferrule is inserted inside the hose, then is clamped in place by the two pieces of the -6AN fitting. You'll need 3/4-inch and 11/16-inch box wrenches for this operation. Before tightening, it's a good idea to check how you want the fitting clocked relative to the steering box end. This will affect how nicely the hose runs between the box and pump.
